LGA 1156 and 1366

[parttimetechie]

What are the differences between these two socket types? I am looking into building a computer for my brother, and the 1156 socket seems to be going out of style. As far as RAM, can I use Dual Channel RAM with this chip? Also, the Chip says 64 bit processing so does this mean I can only use a 64bit version of Windows?

Any guides or directions to the differences would be greatly appreciated.

that is the board I plan to use, can I use DDR3 Dual Channel memory with this board? Newegg says no, but Microcenter says yes.

I won't go into the finer points of difference between the two sockets, but the 1366 is higher performing and runs triple-channel RAM.

You can run RAM in dual channel, but you would lose performance when it's designed for triple.

You don't have to run x64 OS'. Of course if you're running 4+GB RAM (which you should be in 2011), then it would be silly not to.

If you're looking for something thats CPU-intensive (i.e. gaming, video rendering, etc), then 1366 is good, otherwise 1156 is perfectly sufficient.

The difference between LGA 1156 and 1366 is 210 pins, and the ability to host different CPU's where the LGA 1156 is geared to more mainstream audiences and the 1366 is designed for more of an enthusiast or powerhouse audience. However the chipsets on the motherboards that go onto these things are a whole different story.

The LGA 1156 has a total of 4 available chipsets to choose from. They are the P55, H55, H57 and the Q67. All four have a DMI Bus Interface which are rated at 2 GB/s and that's where the similarities stop.

The H55 is the low end with only 6 PCI-E channels, to put it in perspective, modern graphics cards use 16 of them, but are nearly fully powered and functional with 8. It does come with an IGP, but can only be host to 12 USB devices.

The P55 is the mid range with 8 PCI-E Lanes, and 14 USB slots, but it doesn't come with an IGP.

The other two, H57 and Q57 are pretty much in a tie with the main difference being TDP, and intel proprietardy features like "Intel® Quiet System Technology" nothing really major. These guys have 8 PCI-E lanes, and can be host to 14 USB devices.


Then of course we have the chipset for the LGA 1366 which comes in one flavor for desktop pc usage and that is the X58. This one has no IGP, but comes with 36 PCI-E lanes, yes 36, i'm not sure about the USB capabilities, but I'm more than sure that it's greater than or equal to the best 1156 chipset.


To go a little further though, these are now considered outdated sockets as intel has just released (and recalled) the LGA 1155 chipset for their low end and mid range CPU's, and is soon to release the LGA 2011 chipset for the High end and Enthusiast CPU's.



Whoops, forgot to add.

The 1156's are limited to dual channel memory, and 4 slots of it which allows a max of 16GB of memory, the 1366's are limited to triple-channel memory and 6 slots of it which allows 24GB of memory. I believe the LGA 1155 is similar to the 1156, dual channel with 4 spaces, and the 2011 with QUAD channel and 8 spaces...although I can't verify that.

Any idea if the 1366 chipset will survive into the future, or will it be phased out by the 1155 and 2011 chipsets?

What caused the recall on the 155 sets?

The LGA 1155 is taking the 1156's place, and the 2011 is taking the 1366's place just as the 1156 & 1366 took the LGA 775's place. Sadly, those sockets were a one generation socket only.

The 1155's were recalled due to a fault with the chipsets sata controller. Apparently 5 to 15 percent of users would be affected by deterioration of the line quality or something along those lines after about 2 years of rigorous use. There is a fix in the works but I think by now the damage is already done and the trust is out the window- however the power of the damn CPU's are almost worth ignoring it.

So you would think my best long term use would be to get an 1366 socket and then see what happens? How much difference in performance would there be between the 1366 i7 and a new 2011 or 1155 i7?

1366 is good until Q3 of this year, and then it's being replaced by LGA 2011, so long as there aren't any delays. In terms of performance, there are no benchmarks...BUT the current i5 2600k which is an LGA 1155 is outperforming EVERY Desktop CPU on the market except for the intel Core i7 980X So if it's any show of power I would say that the 2011's will destroy anything currently existing on the desktop CPU market. Not to mention the 2600k is an overclocking beast and even with the 980x overclocked it can compete and beat it in most cases.

Personally I would wait for 2011- but they will be expensive. It's believed that the entry level CPU will be $400 (4 Core), and the most expensive ones being $1,200 (8-Core). Also there is AMD's Bulldozer on the horizon which if I remember is rumored to have a 16 core CPU in there somewhere...but I think Sandy Bridge will outperform it, but not in price. Could you imagine a 16 Core CPU for $400?

Is there any indication when the 1155 motherboards will be re released?

Everyone claims that it will be by March and speculates that the real release will be released LATE March to early April. I pretty much don't have a clue where it's going and I'm doing as much research as I can. I like to keep my head above the water when it comes to computer components technology and the news that goes along with it.
